AI Technical Summary

Technical Problem

In the prior art, the temperature of high manganese pig iron is too different from the temperature of the steel in the ladle, which causes the steel and steel slag to splash and burn the staff, which is prone to fire. Tons of bags of high manganese pig iron are scattered, and employees are labor-intensive and cannot control when to discharge the material.

Method used

A pig iron feeder is designed, including a main board, a steelmaking furnace, first and second feed pipes, a hopper, an adjustment structure, an air inlet, an air outlet, a communication pipe and a processing box. Through the synchronous operation of the two first motors, the rotation shaft and baffle are driven to rotate, so that the material falls into the steelmaking furnace; the fan is driven to rotate through the second motor, black smoke is sucked in the steelmaking furnace, and purified by the activated carbon plate.

Benefits of technology

It effectively avoids the scattering of materials and the splash of steel and steel slag, reduces the harm to staff, improves the control and safety of feeding, and improves environmental protection conditions by purifying the black smoke in the treatment box.

Abstract

The utility model provides a pig iron feeder, which relates to the technical field of steelmaking and comprises a main plate, a steelmaking furnace is mounted at the top end of the main plate, a first feeding pipe is fixed at the top end of the steelmaking furnace, a second feeding pipe is arranged at the top end of the first feeding pipe, and a hopper is fixed at the top end of the second feeding pipe. An adjusting structure used for controlling discharging of materials in the hopper is arranged in the second feeding pipe, an air inlet is formed in one end of the second feeding pipe, and an air outlet is formed in the other end of the second feeding pipe. Two rotating shafts are driven to rotate through synchronous operation of two first motors, so that two baffles are rotationally opened, at the moment, materials in a hopper can fall into a steel-making furnace due to the fact that the materials are not limited by the baffles, the feeding effect is achieved, and through arrangement of a first feeding pipe and a second feeding pipe, on one hand, the materials are prevented from scattering and hurting workers, and on the other hand, the feeding efficiency is improved. On the other hand, the problem that a large amount of molten steel and steel slag splash due to traditional hoisting feeding is solved, and practicability is higher.
